"Removed old water heater and installed new water heater and brought water heater up to code. They arrived on time and performed the work efficiently and neatly. The price for the direct vent water heater plus installation was about $250 less than another local quote. Overall I am very satisfied with the price and quality of the installation."

"We had another plumbing company come out due to a leak. Rather than do any diagnostics, they just replaced the pressure valve. It still leaked. I called the next Monday and was told oh, you need a new water heater. Johnny Gavilan from Preferred Home Services checked a couple things and found our expansion tank was bad. He did warn us there still could be a problem with the water heater but at least he checked first. If we need the water heater replaced, our expansion tank will be new!"

Water Heaters FAQs, answered by experts

Several signs indicate your water heater may be failing or in need of replacement. Key indicators include:

  • Age: A water heater older than ten years is approaching the end of its typical lifespan.

  • Water Quality: If you notice rusty or discolored water from your hot water faucets, or a foul odor similar to rotten eggs or sulfur, it can signal internal corrosion.

  • Unusual Noises: Banging, rumbling, or popping sounds from the tank often mean sediment has built up, causing the unit to overheat.

  • Leaks: Any water pooling around the base of the tank or visible leaks are clear signs of failure.

  • Performance Issues: A decline in performance, such as water not getting hot enough, taking longer to heat up, low water pressure, or decreased efficiency, suggests the unit is struggling.

  • Visible Damage: Obvious rust and corrosion on the exterior of the tank can indicate a more serious internal problem.

While these signs often point to replacement, some issues may be fixable. It's best to consult a professional plumber to diagnose the problem before investing in a new unit.

Traditional gas or electric water heaters last an average of six to 11 years. However, with excellent maintenance, they can last up to 15 years. Heat pump water heaters, on the other hand, last an average of between 12 and 15 years and potentially longer with proper maintenance. In both cases, your home's water quality can be a determining factor regarding the lifespan of your water heater.

Water heater installation code requirements are in place to keep your family and home safe. Water heaters that are installed wrong can simply not work. However, that's an, if you're lucky, type of situation. More commonly, incorrectly installed water heaters pose a real threat from carbon monoxide poisoning, gas leaks, water leaks, and even explosions. 

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

Every type of water heater has its advantages and disadvantages. Understanding those can help you decide the best type for your situation and budget.
